Electrical short / Spa Light

[SixPapaCharlie]

Things have been fine, no changes.

I flip the spa light on and the GFCI deal pops on an outlet near the controls.
The spa and pool lights go out.

I reset it. Turn the pool light on and it is fine.
Turn on the spa light and once again, it pops.

Is the first step just replacing that entire spa light? It is a color changing LED one so it means pulling out the cable and re doing the whole thing.

Is there a way to confirm it is a bad spa light before I drop $300 on another one?

Disregard.

I opened up the light and it was full of water.
I dried it out and rebuilt it w/ lots of silicone caulk and now it is working.
